Reuse of Borehole Water

LoadingAdd to my saved searches

The Mace team at University College London implemented a measure to reduce water consumption whilst drilling a second borehole.

When WJ groundwater drilled the first of two boreholes for the geothermal loop, they used 213m3 of water.

The majority of this was lost during the drilling process in the chalk fissures.

To prevent this high water usage during the drilling of the second borehole water was pumped from the first borehole and recirculated back into the aquifer.

This saved both time and water. Only 10m3 of water from the mains was used during the drilling of the second borehole.

This also reduced the volume of water into the Thames Water network.
